Description

  TECHNICAL FIELD The present invention relates to an apparatus for supplying rice cakes such as nigiri sushi (formed vinegared rice into a predetermined shape) to a container.

  2. Description of the Related Art Conventionally, there is a well-known supply device that can hold a well-made product manufactured using a home-made product and transfer it to a container and place it on a predetermined position on the container.

  For example, Japanese Patent No. 3741836 discloses a rice bowl that includes a holding means for holding a rice ball, a driving means for moving the holding means, and a power source for supplying power to the driving means. A feeding device is disclosed.

  However, the structure of this sharitama supply device is complicated because the driving means for moving the clamping means (39a, 39b) is composed of a large number of members (19, 25, 36, 39c, 39d, 40). . In addition, since the nipping means (39a, 39b) is opened by the projecting portions (39c, 39d) coming into contact with the tension spring (40) above the sharitama (a), There exists a fault that a small piece etc. may fall on a rice ball (a), and is unpreferable on hygiene. Furthermore, the extension part (39g) of one clamping piece (39b) is brought into contact with the cam surface of the cam (36), and each clamping piece (39a, 39b) is opened and closed by the rotation of the cam (36). Because of the structure, there is a problem that when the state of holding the staple (a) is released, the adjacent staples are pushed away by the opening operation of each clamping piece (39a, 39b). In order to cope with this problem, when the stabbing ball supply device releases the state where the stabbing ball (a) is sandwiched, the top surface of the stabbing ball (a) is pressed by the support piece (49a), and each clamping piece ( 39a, 39b) are raised without opening. However, this coping method requires a driving means and a power source for causing the support piece (49a) to perform a predetermined operation, and there is a problem that the structure of the apparatus becomes more complicated. Furthermore, in this coping method, in order to raise each clamping piece (39a, 39b) without opening operation, the front-end | tip of each clamping piece (39a, 39b) is flat form. Therefore, since the building stone (a) is transferred in a state where it is sandwiched between only two planes, the building stone (a) may fall off during the transfer.

And a control unit 50.

  As shown in FIG. 4, the sandwiching unit 10 includes a sandwiching means 11 for sandwiching the building ball 60, a drive means 12 for moving the sandwiching means 11, and a power source for supplying power to the drive means 12. 13.

  The clamping means 11 includes a pair of clamping pieces, that is, a first clamping piece 11a and a second clamping piece 11b. The first sandwiching piece 11a and the second sandwiching piece 11b are arranged to face each other, and claws 11c and 11d projecting inward are provided at their tips, respectively (see FIG. 4). As the first sandwiching piece 11a and the second sandwiching piece 11b, it is preferable to employ ones that are not easily deformed in order to have a sandwiching force necessary to sandwich the building ball 60. Moreover, it is preferable that the 1st clamping piece 11a and the 2nd clamping piece 11b are a material which does not corrode easily from a sanitary viewpoint. The 1st clamping piece 11a and the 2nd clamping piece 11b employ | adopted by the present Example are the products made from a hard plastic.

  The driving unit 12 includes three magnets, that is, a first magnet 12a, a second magnet 12b, and a third magnet 12c. The 1st magnet 12a is shape | molded by the cylinder, and is arrange | positioned so that the outer peripheral surface may rotate in a horizontal direction. The second magnet 12b and the third magnet 12c are arranged on both sides of the first magnet 12a so as not to contact the first magnet 12a. The second magnet 12b and the third magnet 12c are also formed into a cylinder like the first magnet 12a. However, the second magnet 12b and the third magnet 12c are different from the first magnet 12a, and their outer peripheral surfaces are different from each other. Arranged to rotate vertically.

  The first magnet 12a rotates in two directions by power supplied from a motor that is a power source 13. That is, the first magnet 12a rotates in one direction when the output shaft of the motor 13 rotates forward, and rotates in the opposite direction when the output shaft of the motor 13 reverses. It has become.

  The rotation directions of the second magnet 12b and the third magnet 12c change depending on the rotation direction of the first magnet 12a due to the magnetic force acting between the second magnet 12b and the third magnet 12a. Specifically, the second magnet 12b rotates clockwise in FIG. 4 when the first magnet 12a rotates in one direction, and in FIG. 4 when the first magnet 12a rotates in the reverse direction. Rotates counterclockwise. The third magnet 12c rotates counterclockwise in FIG. 4 when the first magnet 12a rotates in one direction, and rotates clockwise in FIG. 4 when the first magnet 12a rotates in the reverse direction. Rotate.

  One end of the first arm 12e is attached to the first shaft 12d that is located at the center of the second magnet 12b and rotates together with the second magnet 12b, and the other end of the first arm 12e is connected to the first shaft 12d. It swings with the rotation of. One end of the second arm 12g is attached to the second shaft 12f that is located at the center of the third magnet 12c and rotates together with the third magnet 12c, and the other end of the second arm 12g is connected to the second shaft 12f. It swings with the rotation of.

  In this embodiment, the first holding piece 11a is detachably attached to the other end of the first arm 12e using a fixing screw 14a, and the second holding piece 11b has a fixing screw 14b attached to the other end of the second arm 12g. And is detachably attached (see FIGS. 4 and 5). With this configuration, it is possible to reduce the burden on the user during maintenance. That is, in the conventional apparatus, the entire holding unit must be removed and cleaned. However, according to the configuration of the present apparatus, it is not necessary to remove the entire holding unit 10, and the first holding piece 11 a in contact with the stylus 60 is used. In addition, since only the second clamping piece 11b can be removed and cleaned, it is possible to reduce the time and labor spent for maintenance.

  The vertical movement means 20 is a means for moving the clamping unit 10 in the vertical direction (z-axis direction), and is interposed between the motor 21 and the motor 21 and the clamping unit 10 as shown in FIG. And a crank 22 that converts the rotational motion of the motor 21 into a reciprocating motion in the vertical direction (z-axis direction) and moves the clamping unit 10 up and down.

  The first horizontal moving means 30 is means for moving the clamping unit 10 in the horizontal direction (x-axis direction). As shown in FIG. 6, the guide rail 31 and the slider 32 that travels on the guide rail 31 are provided. The connecting member 33 that connects the slider 32 and the clamping unit 10 is provided.

  The second horizontal moving means 40 is a means for moving the container 70 supplied with the building ball 60 in the horizontal direction (y-axis direction), and the container 70 is installed as shown in FIGS. And a drive unit 42 that moves the table 41 in the horizontal direction (y-axis direction).

  As shown in FIG. 6, the present apparatus configured as described above is installed adjacent to the rice ball manufacturing apparatus 100 and operates as follows. That is, first, the sandwiching unit 10 is disposed above the building stone 60 manufactured using the building glass manufacturing apparatus 100 (see FIGS. 6 and 7 (1)). Next, the motor 21 which is a power source of the vertical moving means 20 is operated, the crank 22 is moved, and the clamping unit 10 is lowered to a predetermined position (see FIG. 7 (2)). Next, the motor 13 which is a power source of the clamping unit 10 is operated, and the output shaft of the motor 13 is rotated forward. Accordingly, the first magnet 12a rotates in one direction, and accordingly, the second magnet 12b rotates counterclockwise and the third magnet 12c rotates clockwise (see FIG. 7 (3)). The rotation of the second magnet 12b and the third magnet 12c at this time causes the first arm 12e and the second arm 12g to swing inward, and the first clamping piece 11a and the second clamping piece 11b are closed accordingly. Then, the building ball 60 is clamped (see FIG. 7 (3)).

  If the stabbing balls 60 are clamped in this way, the motor 13 is stopped, then the motor 21 that is the power source of the vertical moving means 20 is operated, the crank 22 is moved, and the clamping unit 10 is moved to a predetermined position. Raise (see FIG. 7 (4)). Next, the 1st horizontal moving means 30 is operated, the clamping unit 10 is moved to a horizontal direction (x-axis direction), and is arrange | positioned above the container 70 (refer FIG.6 and FIG.7 (5)). At this time, the front end of the first sandwiching piece 11a and the front end of the second sandwiching piece 11b are provided with claws 11c and 11d projecting inward, so that the pastry ball 60 falls off during the transfer of the pastry ball 60. This can be surely prevented.

  Next, the motor 21 which is a power source of the vertical moving means 20 is operated, the crank 22 is moved, and the clamping unit 10 is lowered to a predetermined position (see FIG. 7 (6)). Next, the motor 13 that is a power source of the clamping unit 10 is operated to reverse the output shaft of the motor 13. As a result, the first magnet 12a rotates in the reverse direction, and accordingly, the second magnet 12b rotates in the clockwise direction and the third magnet 12c rotates in the counterclockwise direction (see FIG. 7 (7)). The rotation of the second magnet 12b and the third magnet 12c at this time causes the first arm 12e and the second arm 12g to swing outward, and the first clamping piece 11a and the second clamping piece 11b open accordingly. Then, the building ball 60 is released (see FIG. 7 (7)). At this time, if there is an adjacent building piece 60, the first holding piece 11a and / or the second holding piece 11b will collide with the adjacent building piece 60. According to the present apparatus, Since the rotation of the second magnet 12b and / or the third magnet 12c stops and the first magnet 12a idles when the sandwiching piece 11a and / or the second sandwiching piece 11b collides with the adjacent building ball 60, the first magnet 12a idles. The adjacent sushi balls 60 are not pushed away by the first clamping piece 11a and / or the second clamping piece 11b. This is because when the first clamping piece 11a and / or the second clamping piece 11b comes into contact with the adjacent staving balls 60, play occurs in the transmission of power to the first clamping piece 11a and / or the second clamping piece 11b. This is because the opening operation thereof is suppressed, or the force of pushing the building ball 60 is reduced. The experimental results on this point will be described later.

  If the rice ball 60 is placed on the container 70 in this way, the motor 21 that is the power source of the vertical moving means 20 is then operated, the crank 22 is moved, and the clamping unit 10 is raised to a predetermined position. (See FIG. 7 (8)). When the contact state between the first sandwiching piece 11a and / or the second sandwiching piece 11b and the adjacent staving balls 60 is released during the ascent of the sandwiching unit 10, the rotation of the second magnet 12b and / or the third magnet 12c is performed. Is resumed, and the first clamping piece 11a and / or the second clamping piece 11b is opened.

  If the clamping unit 10 is raised to a predetermined position, the motors 13 and 21 are stopped, and then the first horizontal moving means 30 is operated to move the clamping unit 10 in the horizontal direction (x-axis direction). It arrange | positions again on the top of the stab ball 60 on the turntable 111 of the sash ball manufacturing apparatus 100 (refer FIG. 6). The apparatus repeats the above-described operation, and when supplying the rice balls 60 while changing the row on the container 70, the second horizontal moving means 40 is operated to move the table 41 in the horizontal direction (y-axis direction). Move. Eventually, a large number of bowls 60 can be arranged and supplied on the container 70 at minute intervals.

  At sushi restaurants, etc., sushi is provided in containers so that customers can take home sushi. However, if the spacing between the sushi balls on the container is too wide, the appearance will deteriorate. For this reason, it is considered that the interval between the two pieces is preferably about 3 mm. According to this apparatus, it is possible to arrange and supply a large number of styling balls 60 on the container 70 with the interval between the styling balls 60 being about 3 mm. Moreover, according to this apparatus, since the 1st thru | or 3rd magnets 12a-12c employ | adopted as the drive means 12 are non-contact with each other, there is no possibility that the small pieces etc. as wear powder may fall on the building ball 60, It is preferable for hygiene, and since it does not generate sound by contact with each other, it is an optimum structure as a food machine.

  In order to confirm the effect of this apparatus, an experiment was conducted using the comparative example shown in FIG. The clamping unit 10 ′ according to the comparative example is configured such that the driving means 12 ′ includes a worm gear 12h and two worm wheels 12i and 12j that are arranged on both sides of the worm gear 12h and engage with the worm gear 12h, respectively. Different from the clamping unit 10 of the present apparatus.

  Table 1 shows the rotation angle of the first magnet 12a and the rotation angle of the second magnet 12b necessary for displacing the tip of the first clamping piece 11a in the embodiment in the state where there is no serving ball.

  Table 2 shows the rotation angle of the worm gear 12h and the rotation angle of the worm wheel 12i necessary for displacing the tip of the first sandwiching piece 11a 'in the comparative example in the absence of the bead.

  In this experiment, the first sandwiching pieces 11a and 11a ′ of the example and the comparative example are set in a vertical state, and a 18-gram weight is placed on the outer surface of each first sandwiching piece 11a and 11a ′. After that, the motors 13 and 13 ′ of the example and the comparative example were operated, and the displacement (deviation amount) of the building ball when the first clamping pieces 11 a and 11 a ′ were opened was measured. In addition, because the sticky ball may not be displaced immediately even if pressed due to its adhesiveness, the first magnet 12a and the worm gear 12a ′ are each held at a predetermined rotation angle (that is, without the sticky ball). Displacement of the building stone was measured for each elapsed time from when the tip of the pieces 11a and 11a ′ reached a rotation angle required to displace 0 to 3 mm. Table 3 shows the results of the examples and Table 4 shows the results of the comparative examples.

  From this experimental result, in the configuration in which play does not easily occur in the transmission of power to the first clamping piece 11a ′ as in the comparative example or the configuration in which the loss of power transmitted to the first clamping piece 11a ′ is small, the first clamping piece 11a. Even if the stabbing ball is in contact with the outer surface of ', the worm wheel 12i rotates with the rotation of the worm gear 12h, so the opening operation of the first clamping piece 11a' is not suppressed, or It can be seen that the pushing force is strong, so it pushes out the rice.

  In contrast, according to the present apparatus (example), the first to third magnets 12a to 12c that are not in contact with each other are employed as the driving means 12, so that the first sandwiching piece 11a is in contact with the building ball. Further, play occurs in the transmission of power to the first sandwiching piece 11a, that is, the rotation of the second magnet 12b stops even if the first magnet 12a continues to rotate, and therefore the opening operation of the first sandwiching piece 11a is suppressed. Or, the force that pushes the building stone is reduced, and the building ball is hardly displaced. Therefore, according to the present apparatus, it is possible to effectively prevent the adjoining building stones from being pushed away.
